“The average monthly premium for a Silver plan ranges between $938 and $1,452 for a family of four earning $51,000. Even with a federal subsidy, that could mean an out-of-pocket cost of $500 or more per month to have coverage that still requires Florida families to pay about 30% of expenses out-of-pocket for deductibles, copayments, and coinsurance,” an OIR statement reads.

“The rate information released (Monday) applies to (Obamacare)-compliant individual plans both on and off the exchange,” an OIR spokesman told Watchdog.org in an email.

The state regulatory agency didn’t offer any reasons for the premium increases, but Florida Blue, the state’s largest health insurance provider, blames rising costs on an influx of older adults who are using more services, according to the Kaiser Family Foundation.

Florida Blue announced Friday it would raise all of its Obamacare exchange prices by 17.6 percent.

“The issue to watch will be if younger and healthier individuals remain outside of the ACA (exchange) plans for good,” said Josh Archambault, a senior fellow at the market-oriented Foundation for Government Accountability.

“If so, then we can expect to see significant premium increases each year, and taxpayers will be paying a bigger and bigger share for subsidies being granted to lower-income individuals,” he said.

State lawmakers revoked OIR’s ability to reject rate filings last year. But according to a collaborative agreement between the U.S. Department of Health and Human Services and the state of Florida, HHS will conduct a final review of the rate filings.
